Answer 5

How does randomization in an experiment combat response bias?
A. When subjects are randomly assigned to treatment and control groups, they will not exhibit response bias.
B. In a simple random sample chosen from the population, there will be no response bias.
C. If the experimenter does not know which subjects are in the treatment group, he or she will not mistakenly cause response bias.
D. All the subjects that are biased one way get assigned to the treatment group.
E. Response bias cannot be eliminated, but it should cancel out between the treatment and control groups.

Answer 13

Presume the responses do not change based on the experiments design (unless it quantum physics). any bias in the experiment would be a result of grouping similar (or opposing) subject together. thus true randomization limits the amount of bias and can be "measured" by probability theory. C is the best answer, because the responses don;t change, we hope that the effects are cancelled by randomizing the groupings
